AdBlue in diesel in Dartford, drained on the spot
Stop, switch nothing on, and call 01295 380724. Local drainers across Dartford handle adblue in diesel every week: tank out, lines flushed, clean fuel in, all where the vehicle is parked. Expect 1 to 3 hours on site and a call-out from £89, with the full price given before they leave for you.
AdBlue belongs in the blue-capped tank. In the diesel tank it attacks the fuel system and has to be drained out before the engine runs. Left sitting in the tank, it is a small job.

The drain itself, step by step in Dartford
They bring the fuel. Once the tank is empty and the lines are flushed, the drainer adds enough of the correct fuel to get the engine running and to reach a filling station, then checks for warning lights before handing the keys back.
Five things to ask a drainer before they set off
A drainer should be happy to answer all of these on the phone. If they will not give a price before travelling, ring someone else.
- What is the total, not just the call-out, if it is a straight drain?
- Will you check the filter and pump if the engine ran?
- How much more if the engine has already been started?
- Is there an extra charge at night or at the weekend?
- Do you take card payment at the roadside?
What to do right now
- Leave the key out of the ignition and do not unlock the steering to push the car.
- If you are at the pump, tell the cashier; most forecourts will let the car stay in a bay.
- Call 01295 380724. Say what fuel went in, roughly how much, and where you are.
- Agree the price on the phone. Nobody travels until you have.
- The drainer pumps out the tank, flushes the lines and adds clean fuel.
- They start the engine, check it runs cleanly and take the old fuel away.

From the drainer's notebook
Fuel Fixer, the company behind Wrong Fuel Drain, holds a rating of 4.8 out of 5 from 2,190 reviews on Trustpilot, on a profile claimed since 2017.
Across recent reviews, the themes customers raise most often are staff who stay polite, professional and reassuring during what is a stressful situation, and how quickly a technician arrives and gets the vehicle back on the road in Dartford.
The most common criticism is price. Some customers have felt the cost of an emergency drain was steep for a job that takes under two hours, and that is fair comment on an emergency call-out. It is why the misfuel call-out fee now starts at just £89 and why the full figure is quoted on the phone before a technician sets off — so nothing about the cost is a surprise at the roadside.
Common questions
Do you cover all of Dartford?
Yes — forecourts, roadsides, homes and workplaces across Dartford and the surrounding area.
Is the drain messy?
No. The fuel is pumped into a sealed tank on the van, and a drip tray catches anything from the connection. The area is left as it was.
Do you work at night in Dartford?
Yes. Drainers work 24 hours a day, including weekends and bank holidays.
Do I need to move the car off the forecourt?
Only if it is blocking a pump. Push it into a bay with help and the engine off; the drainer can work there.
Do I need to stay with the car?
Ideally yes, so the drainer can confirm what happened and hand the keys back. If not, agree access on the phone.
What happens to the fuel you take out?
It goes into a sealed tank on the drainer's van and is taken for licensed disposal and recycling. It is never tipped away.
